The CPU (Central Processing Unit) is the "brain" of the computer, responsible for executing instructions. It performs this task through a repetitive cycle: Fetch, Decode, Execute. This cycle repeats continuously, allowing the CPU to process a large number of instructions in a short period, enabling the computer to perform tasks and run programs.
